Summary
Between Sep 21 and Sep 24, 2026, customers using our e-Invoicing services for Poland experienced delays in invoice clearance submissions and the retrieval of documents. Most transactions submitted during this period were delayed rather than lost, and all affected documents have since been processed. The issue has been fully resolved and the service is operating normally.
Root cause
The delay was caused by an issue affecting part of the process we use to retrieve inbound documents for Poland. A configuration change introduced during a system deployment disrupted this process, preventing documents from being retrieved as expected.
Resolution
The issue was identified and the affected process restarted, restoring normal document retrieval. We then confirmed that all previously delayed transactions had been fully processed and that the service was operating normally.
Preventive measures
The configuration involved in this issue has been reviewed and adjusted, and a wider review of the deployment process is underway to reduce the risk of a similar disruption in future.
